main features

The instrument adopts a fully digital output design. The signal is converted to logarithmic and zeroed by a microcontroller after 24 bit A/D processing, and the processed result is sent to the RS232 interface.

This instrument can control the wavelength composition.

This instrument can implement automatic spectral scanning with flow interruption. Scanning speed: wavelength 1/second

The optical path of this product can be adjusted by changing the flow cell and corresponding system parameters. It can be easily converted from analytical type to semi preparation or even large-scale preparation type.

This product has an analog output port.

This product can be controlled by a chromatography workstation through an RS232 interface.
